Features At A Glance

PRODUCTIVITY

The 789 delivers a faster speed on grade than competitive trucks thanks to the efficient 3516E 16-cylinder engine and mechanical drivetrain.
Expanded tire options allow mines to take advantage of higher speeds, particularly in flat, long-haul, high-speed applications.
The Advanced Power Electronic Control Strategy (APECS) enables faster cycle times and faster acceleration thanks to more continuous torque and rimpull.
The 789 has an empty machine weight advantage, allowing it to haul more with every load, delivering a cost per ton advantage over competitive trucks.
Productivity-enhancing features such as Hill Start Assist with Anti-Rollback, Enhanced Traction Control, Dynamic Stability Control (DSC), Anti-lock Brake System (ABS), Machine Speed Limiting and Cruise Control improve machine responsiveness and controllability while improving cycle times and reducing operator fatigue.

SAFETY

Wide, slip-resistant surfaces and hand rails, plus an optional powered access ladder, improve access and egress.
Superior control is delivered by a patented braking system that provides immediate, fade-resistant braking and retarding.
Visibility is enhanced by wide-angle mirrors plus an optional 360-degree Surround View camera, which offers a bird’s-eye view.
The Cat MineStar™ Object Detection system combines radar and camera systems to warn operators about light vehicles or stationary hazards within the immediate vicinity of their machines.
The optional Driver Safety System alerts the operator if fatigue or distraction are detected.

OPERATOR COMFORT

The cab provides 34% more operator space than D-Series models. It’s 17% wider and offers 11% more legroom and 19% more shoulder room.
Controls, levers and switches are positioned for ease of use.
With 40% less Sound Pressure Level (SPL), automated temperature control and cab filtration, operators enjoy a safer and more comfortable environment.
A walkthrough cab with fully adjustable center console, easy-to-adjust seat and increased leg room make the cab ideal for operators of all sizes.
The next generation seat is four-point-restraint ready and incorporates features like thigh tilt and extensions, air adjustable side and lumbar bolsters, and heated and cooled cushions.

OPERATOR EFFICIENCY & PRODUCTIVITY

Higher resolution displays improve access to information. Machine data, controls and guidance information are consolidated onto two 10-inch screens.
The optional Auto Hoist feature automatically raises the body and controls engine speed, simplifying operation and minimizing cycle times.
Speed coaching gives operators real-time feedback on how to operate the truck to maximize its productivity.
The payload monitoring system comes with more accurate measurements, providing immediate feedback to the operator.

SERVICEABILITY

The new modular HVAC (heating, ventilation and air conditioning) system improves reliability and consolidates components so the entire system can be removed and replaced quickly.
A modular radiator reduces engine removal and installation time and enables rebuilds to be completed off the truck.
New remote flash and remote troubleshooting capabilities provide immediate access to the latest software updates and make it possible to troubleshoot the machine remotely.
Time spent on regular maintenance procedures is reduced thanks to features such as extended service intervals; ground-level access to tanks, filters, drains and engine shutdown; easier access to daily service points as well as major components; a maintenance platform with access to the engine; and optional fast-fill service center.
A 100% airless electric start option eliminates air system maintenance from the machine and improves uptime.

DURABILITY AND LONG LIFE

The 789 frame uses a box-section design, incorporating two forgings and 21 castings in high-stress areas with deep penetrating and continuous wrap-around welds to resist damage from twisting loads without adding extra weight. The mild steel frame provides flexibility, durability and resistance to impact loads.
Resiliently mounted to the main frame to reduce vibration and sound, the integral ROPS is designed as an extension of the truck frame.
Component life is enhanced thanks to the standard rear-axle continuous filtration feature. Cleaner oil helps promote lubrication that leads to longer life
The frame, powertrain, engine and components are built to be rebuilt — delivering multiple lives of like-new performance at a fraction-of-new price.

CAT BODIES

Cat bodies are the best choice for the 789. They’re designed to be an integral part of the entire vehicle system, ensuring you achieve maximum chassis life.
The High Performance (HP) body features a lightweight, simplified and durable design that provides complete front machine coverage and extended overhead protection.
Available in several sizes, the MSD II body is ideal for mature mines with good operational and maintenance practices. It can be lined or unlined, with a site-specific body designed to maximize performance.
Intended for tough applications including greenfield sites and contracting mines, the Dual Slope body provides excellent load retention, maintains a low center of gravity with optimum load distribution and reduces shock loading.
The X Body incorporates the latest structural designs and offers more volume at a lower weight. It uses the Cat Mine Specific Design to create a body that is properly sized to meet the specific requirements of heavy-duty applications.

SUSTAINABILITY

The 789 is designed to use less fuel, which reduces engine emissions, and there is zero fuel burn during retarding. The Tier 4 Final engine reduces NOx and particulate matter.
The Cat 3516E provides emission choices: fuel-optimized engine for less regulated countries or optional engine compliant to U.S. EPA Tier 4 Final / EU Stage V emissions standards.
The 789 engine is compatible with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels.
Features like oil renewal systems, continuous rear axle filtration, extended life filters and longer maintenance intervals decrease the amount of waste contributed to the environment.
By rebuilding machines and components, the Cat Rebuild and Cat Reman programs preserve raw materials, conserve energy and reduce emissions.

VERSATILITY

The Cat 3516E engine has proven its ability to deliver high power and reliability in the most demanding mining applications.
The mechanical drive powertrain and power shift transmission provide unmatched efficiency and control on steep grades, in poor underfoot conditions and on haul roads with high rolling resistance.
Application-specific capabilities are available for extreme ambient conditions and high-altitude applications.
The 789 lets you select the tire offering that best matches your application, with a larger tire for flat, long, high-speed applications. The frame is designed to maintain the same turning diameter while accommodating larger tires.
The 789 is available in two options to meet the emissions standards. The optional Tier 4 Final engine meets the strictest standards while the LRC engine is available in those countries that are less regulated.

TECHNOLOGY SOLUTIONS

MineStar Fleet is a fleet monitoring system that can be used to measure, manage and maximize the overall hauling operation.
Additional Detect offerings include Awareness, which can provide warnings and the in-cab Driver Safety System, which intervenes when it detects fatigue or distraction.
Machine health and condition monitoring solutions enable a proactive approach to maintenance.

Cat Command for Hauling

Cat® MineStar™ Command for hauling takes advantage of the most sophisticated technologies available to deliver a next-generation haulage solution — one that boosts safety, productivity and availability on busy mine sites, especially those in difficult or remote locations. Command provides the fully integrated operation of autonomous mining systems, allowing them to haul more efficiently with near-continuous operation and move more with fewer people on site. Autonomous trucks operate safely around other equipment, light vehicles and personnel. Command trucks respond to calls to the shovel, move into position, haul to dump points and even report for maintenance — all without an operator on board.
